Answer Posted / reza r
Very large and very small values in mathematics can be
mentioned by dB. dB is a logarithmic calculation that
normalizes the value of a factor.
- sign in the value of a signal is because of noting that
the signal is incoming to the antenna (received signal) not
the transmitted one!
